6. Texas Hail Storm, June 6

Thunderstorms produced hail up to the size of baseballs in the Dallas-Forth Worth metro area in the early morning hours of June 6, damaging homes, businesses and automobiles.

When severe storms produce large hail over a major metro area, it typically results in a hefty price tag since a dense population is affected.

The exact cost of this particular hail storm is unknown at this time, but NOAA says it will be the sixth billion-dollar weather disaster of 2018.
